Buck converter using Microcontroller

[innovationhut]

Hi,

I desperately need the circuit design for the buck converter using the pic or any micro controller. I have calculated all the values and know all the components needed, the trouble that I am having is: Interfacing the micro controller to drive the MOSFET, by keeping in mind the high voltage side of the MOSFET and only 5v logic of the micro controller.

I am also using the MOSFET driver to enhance the 5 logic of the micro controller.

Any simple circuit or any kind of block diagram will be highly appreciated.


Thanks in advance

Hi,
Take a look at this:

For interfacing, you need to use a MOSFET driver. Take a look at TC4427 or IR4427:

Hope this helps.
